Sig Sauer ROMEO5 Red Dot 1X20MM Black Finish 2 MOA Dot High Mount Only Fits M1913 Rail

Product Description

The Sig Sauer ROMEO5 red dot sight is a 1x20mm non-magnified optic with a 2 MOA dot reticle, black finish, and high mount designed to fit M1913 Picatinny rails. This configuration delivers fast target acquisition for rifles and carbines at close to moderate range.

A 2 MOA dot provides a clean aiming point that covers roughly 2 inches at 100 yards. That size balances precision and visibility for most defensive and recreational shooting applications.

The high mount raises the optic above the rail for proper eye alignment on AR-15 platforms and similar rifles with raised cheek positions. The M1913 Picatinny interface is the standard NATO-spec rail found on most modern tactical rifles.

• Mount Type: High mount for M1913 rail

What the 2 MOA Reticle Means for Shooting

A 2 MOA (minute-of-angle) dot subtends approximately 2 inches per 100 yards of distance. At 50 yards, the dot covers about 1 inch. At 200 yards, it spans roughly 4 inches. This size works well for rapid engagement at close range without obscuring small targets at distance.

Larger dots — 4 MOA or 6 MOA — are faster to pick up under stress but can hide detail on precision shots. Smaller dots offer finer aiming points but may be harder to see in bright light or during quick transitions. The 2 MOA standard splits the difference for general-purpose use.

High Mount and AR-15 Compatibility

The high mount positions the optic to align with the natural eye level when shooting an AR-15 with a standard stock and cheek weld. This configuration is often called absolute co-witness or lower-third co-witness height, depending on the exact measurement, but call 817-393-4000 to confirm the specific height if that matters for your setup.

The M1913 Picatinny rail standard ensures secure attachment to most modern rifles. The rail features evenly spaced transverse slots that lock the mount in place and allow repeatable zero if the optic is removed and reinstalled.

Red Dot Basics for New Buyers

Red dot sights use an LED emitter and a specially coated lens to project a reticle that appears to float at infinity. Both eyes stay open during shooting, which improves peripheral awareness and speeds target tracking compared to magnified scopes.

Because the dot is parallax-free at typical engagement distances, minor head position changes do not shift the point of impact. You simply place the dot on the target and press the trigger. This makes red dots ideal for defensive carbines, competition rifles, and training platforms.

Battery life and brightness settings vary by model and usage pattern. For specifics on runtime and adjustment range for the ROMEO5, call 817-393-4000.

Frequently Asked Questions

Q: Does the Sig Sauer ROMEO5 work on AR-15 rifles?

A: The ROMEO5 fits any rifle with an M1913 Picatinny rail, including AR-15 platforms. The high mount provides proper eye alignment for standard AR stocks and cheek welds.

Q: What is the difference between 2 MOA and 4 MOA red dots?

A: A 2 MOA dot covers about 2 inches at 100 yards, while a 4 MOA dot covers about 4 inches at the same distance. The 2 MOA reticle offers more precision at range, while 4 MOA dots are faster to acquire up close.

Q: Can I mount the ROMEO5 on a shotgun or pistol?

A: Any firearm with an M1913 Picatinny rail can accept this mount. The high-mount configuration may not align properly on pistols or shotguns with lower sight planes, so call 817-393-4000 to confirm fit for non-rifle applications.

Q: Is the red finish on the ROMEO5 the color of the housing or the reticle?

A: The finish attribute refers to internal components or coating. The housing color is black, as stated in the product name. The reticle is a red LED dot.

Q: Do I need a gunsmith to install a red dot sight?

A: Most shooters can install a Picatinny-mount red dot with basic tools. The rail clamp tightens with a hex or Torx fastener. If you prefer professional installation or need the optic bore-sighted, Western Sport offers gunsmithing services in Roanoke.

Q: What is the return policy if the optic does not fit my rifle?

A: Call 817-393-4000 to discuss your specific rifle and mounting setup before ordering. Western Sport can help you confirm compatibility and answer questions about scope rings and mounts to avoid fitment issues.
